The Sharks have promoted Springbok tighthead prop Jannie du Plessis to their starting XV for Friday's Super Rugby clash with the Force in Perth.

Head coach John Plumtree has decided to give the experienced front-row forward a start in place of in-form youngster Wiehahn Herbst this week.

Other changes to the side see Odwa Ndungane come in for Piet Lindeque on the wing while Willem Alberts replaces Jean Deysel at blindside.

The final alteration to the line-up comes at lock where Pieter-Steph du Toit moves to the bench, with Anton Bresler getting a starting jersey.

Plumtree, whose side find themselves in a bad patch of form, warned his men that the Western Force will be a difficult proposition at nib Stadium.

"They beat the Crusaders, they lost by one point to the Chiefs, the 2012 champs, and with those results, they have some belief, it's going to be a tough game, they're a side that's clearly working very hard for each other and we know it is going to be a really tough task from our side," he said.
